Answer:

${x}^{7} - 4 {x}^{5} + 2 {x}^{4} + 4 {x}^{3} - 10$

Step-by-step explanation:

To write a polynomial in descending order means writing the polynomial in decreasing powers of x.

The given polynomial expresion is

$- 4 {x}^{5} + 4 {x}^{3} + {x}^{7} - 10 + 2 {x}^{4}$

We start from the term with the highest degree and end with term with the least degree.

${x}^{7} - 4 {x}^{5} + 2 {x}^{4} + 4 {x}^{3} - 10$

Therefore the given polynomial written in descending order is

${x}^{7} - 4 {x}^{5} + 2 {x}^{4} + 4 {x}^{3} - 10$

Unit 11: volume and surface area<br><br> homework 5: surface area of prisms & cylinders

Monica [59]

The volume and surface area of any prism can be determined using the given formula explained below.

<h3>What is the Volume and Surface Area of Prisms?</h3>

The surface area of any given prism can be calculated using the formula, SA = (2 × Base Area) + (Base perimeter × height).

The volume of any given prism can be determined, using the formula, V = base area × height of the prism.

The image for the prisms to be calculated is missing, howver, using the above formula, the volume and surface area of any prism can be determined using the given parameters.

The sum of two numbers is 54 and the difference is 12 . what are the numbers?

Gnesinka [82]

X + y = 54

x - y = 12

x = 33

y = 21

33 + 21 = 54

33 - 21 = 12

g The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control

Rudiy27

Answer:

0.1426 = 14.26% probability that at least one of the births results in a defect.

Step-by-step explanation:

For each birth, there are only two possible outcomes. Either it results in a defect, or it does not. The probability that a birth results in a defect is independent of any other birth. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control and Prevention (CDC).

This means that $p = \frac{1}{33}$
